Putting her to sleep apparently counts as killing for people who have noticed it.

Mission 7 Slackjaw/Granny When you see these two at the end of Mission 7, it can get kind of screwy, and the best bet is apparently to just pickpocket the key from Granny and run.Mission 7 Daud - Just pickpocket his pouch from him as you go for his key when you finally reach him in Mission 7.This will also grant you the political suicide achievement. Mission 6 Lord Regent - Head up to the broadcast tower and talk to the broadcaster who will tell you it'd be a good idea to get the Lord Regents tapes from his safe (935) and broadcast them over the air to dismantle his government from the top down.After that, figure out a way to get the target into the kitchen so you can knock her out and she can be kidnapped (at least she isn't dead).

Once you've done that, head downstairs and find a man with rabbit/scarecrow type mask that has random whiskers on it, he'll be wandering around the first floor and talk to you about helping him kidnap his love. Mission 5 Lady Boyle - Search the second floor for clues as to which Boyle you need to capture (it changes).Mission 2 Pendeltons - Do the Slackjaw sidequests and he will offer to take care of the Pendelton twins for you if you get the code to the Art Dealer's safe.Mission 1 Overseer Campbell - Either let him poison the Captain and then choke him out, or follow them into the basement and choke him out.You should avoid talking and doing missions for Granny Rags, as her wishes are harm against others.

You must avoid the deaths of all civilians, enemies, hounds, and even weepers.
